摘要
采用多面体低聚倍半硅氧烷(POSS)对聚氨酯(PU)进行改性,并对改性PU的性能进行研究。结果表明:采用超声波分散法可将POSS均匀分散在PU基体中;八乙烯基POSS对PU具有较好的补强和增韧作用,而八苯基POSS对PU的补强作用不明显。
Polyurethane(PU) was modified by polyhedral oligomeric silsesquioxane(POSS),and the properties of modified PU were investigated.The results showed that,POSS was uniformly dispersed in PU matrix by using ultrasonic dispersion method;octavinylsilsesquioxane(OVS) possessed preferable reinforcing and toughening effects,but octaphenylsilsesquioxane(OPS) had no significant reinforcing effect.
